A process is disclosed for converting a methanol-containing feed to a light olefin-containing product over a ZSM-12 zeolite catalyst, preferably modified by incorporation of either magnesium, manganese or both magnesium and manganese. By using such Mg and/or Mn-modified ZSM-12 zeolite catalysts, methanol and/or methyl ether can be converted to an olefin-containing hydrocarbon product enriched in C.sub.2 to C.sub.4 olefins and especially enriched in the particular light olefin propylene.

Catalytic conversion of methanol to light olefins

Organic compound mixtures enriched in meta-isopropylphenol are prepared by alkylating phenol with isopropanol or propylene to form mixtures of isopropylphenol isomers and by subsequently selectively cracking the para-isopropylphenol isomer from such a mixture over a ZSM-5 type cracking catalyst. Concentration of the para-isomer is thereby selectively reduced relative to the meta-isomer and the meta-isopropylphenol isomer can be further separated from the remaining mixture by fractionation procedures.

Production of meta-isopropylphenolic products

Succinimides of aminoaryl sulfonic acid salts provide exceptional detergency, viscosity control and anticorrosion properties to lubricants and greases and to other fluid compositions useful in hydraulic systems. Ammonium, alkylammonium, alkali metal, alkaline earth metal and groups IB, IIB, VIB, VIIB, VIII metal salts of aminoaryl sulfonic acid salts, and the salts of sulfanilic acid in particular, can be reacted with alkenyl or alkylsuccinic anhydride, acid or ester, in which the alkenyl or alkyl group may contain from 8 to about 500 carbon atoms, to yield the products of this invention. These products are understood to be novel. Suitable modifications of the aforementioned are the succinimides of di(aminoaryl sulfonic acid) salts, aniline disulfonic acid salts and corresponding aminonaphthalene sulfonate salts which are also useful in the compositions of this invention.
